O l L C U P SPECIFICATION forming part of Letters Patent No. 552,737,dated January "i, 1896.

Application filed August 10, 1895. Serial No. 558,901. (No model.)

To all whom t may concern,.-

Beit known that I, FRANKDREW WINKLEY, a citizen of the United States,residing at Madison,in the county of Dane and State of Wisconsin, haveinvented certain new and useful Improvements in Oil-Cups, of which thefollowing is a specification, reference being had therein to theaccompanying drawings.

My invention is an oil-cup for bicycles and the like, and is animprovement over the cup shown in Letters Patent granted to me March l5,1892, No. 470,734..

My invention includes a body which is made tubular to hold the oil, anda cap covering the body and provided with a cut-away portion adapted toregister with or to cover the opening for the oil in the body, the coverand body being held together by means of a spring, which whilepreventing the parts from becoming detached also operates to place asufficient amount of friction on the cap to prevent too free movement onthe body, but at the same time the detachment of the partsmay beaccomplished when desired.

In the drawings, Figure 1 shows a sectional view of the cup; Fig. 2, anelevation, and Fig. 3 a detail of the parts detached and separated.

In the drawings, A represents the body or post, which is screw-threadedat its lower end for attachment to the part to be lubricated, having anotch at its upper end for use of a screwdriver, and this is providedwith an oilopening a, leading to the interior of the body. It isdesirable to cover this opening ce, so as to prevent dust or likematerial from passing to the interior, and for this purpose I provide acap l?, which fits over the body. This cap has a flange which extendsdown below the oil-opening except at one point where the cap is cutaway, and when this cutaway portion registers with the oil-opening theoil may be injected into the opening. Vhen turned out of register, theflange of the cap completely covers and protects this opening.

It is the object of the present invention to provide a simple form ofconnection between the body and the cap; and to this end I form a groovein the periphery of the upper end of the body, as shown at e', and sinka hole centrally of this groove above the oil-opening a. The cap isprovided with a like groove f, which when in position with the bodyregisters with the groove e. In order to hold the parts together, I takea piece of spring metal g, curved into a circular form and having oneend bent at right angles, as shown at h. This end I insert in the holewith the curved portion extending to one side, and then place the capover the body with its cut-away portion in line with the hole containingthe bent end of the wire spring. The cap is then turned, and this laysthe wire in the groove in the body,

and as soon as the end of the wire disappears in the groove the cap ispressed down to its full extent, with the result that the spring engageswith its groove and thus holds the parts together. By this arrangementone end of the spring is attached to the cap, and the resiliency of thefree portion thereof will cause it to press against the wall of thegroove in the cap,and thereby prevent the accidental rotation of thesame.

4What I claim is- In combination, an oil cup provided with a groove, acover therefor having an opening therein registering with a llingopening in the cup, and being provided with a groove registering withthe groove in the cup, and a spring secured at one end to the cupfitting said grooves,the resiliency of the spring keeping its freeportion pressed against the wall of the groove in the cover, whereby africtional restraint is exerted by said spring to prevent the turning ofsaid cap, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

FRANK DREW VINKLEY.
